She makes simple calculation mistakes pretty often and gets annoyed when you point them out. That's also her general attitude towards you; you are an annoyance to her (atleast that's how i feel). Anyway at the end of the day, it's not hard to get an A in her course, cause she curves like no tomorrow. Don't take a course with her unless you have to

Worthless teacher. Professor Ruimi assumes students are itiots. Very defensive if you correct her. Says things like, "it's just a detail," or "it's only algebra, of course I know how to do this problem," when she's struggling over examples in lecture. Don't take a class from her. It is painful.
